| transmission of lungworms of harbour porpoises and harbour seals: molecular tools determine potential vertebrate intermediate hosts. | harbour porpoises (phocoena phocoena) and harbour seals (phoca vitulina) from german waters are infected by six species of lungworms (metastrongyloidea). these nematodes parasitise the respiratory tract, are pathogenic and often cause secondary bacterial infections. in spite of their clinical and epidemiological significance, the life cycle and biology of lungworms in the marine environment is still largely unknown. regions of ribosomal dna (its-2) of all lungworms parasitising harbour porpoises ... | 2010 | 20123100 |
| efficacy of ivermectin and moxidectin against otostrongylus circumlitus and parafilaroides gymnurus in harbour seals (phoca vitulina). | verminous bronchopneumonia caused by infection with otostrongylus circumlitus and parafilaroides gymnurus is an important cause of death during the rehabilitation of harbour seals (phoca vitulina). during the winter of 2000/01, 35 juvenile harbour seals with severe clinical signs of verminous bronchopneumonia were treated with either 0.2 mg/kg ivermectin orally or 0.2 mg/kg moxidectin subcutaneously, and monitored for 30 days. the efficacy of the anthelmintics was determined by the pattern of la ... | 2003 | 12585598 |
| the helminth fauna from the common seal (phoca vitulina vitulina, linné, 1758) of the wadden sea in lower saxony. part 2: nematodes. | during the seal epidemic in 1988 and the beginning of 1989, 115 common seals found dead on the shores of the wadden sea of lower saxony were investigated for the presence of nematodes. the lungworm otostrongylus circumlitus railliet 1899 was found in 26.1% of the seals, the lungworm parafilaroides gymnurus railliet 1899 in 26.9% and the heartworm dipetalonema spirocauda leidy 1858 in 32.2% of the seals. in the digestive tract, two anisakid species were found, pseudoterranova decipiens mozgovoi 1 ... | 1991 | 1789022 |
| histopathological findings in harbour seals (phoca vitulina) found dead on the german north sea coast. | various organs--lung, trachea, liver, kidney, heart, adrenal gland, skin, spleen, thymus, lymph node, gut, thyroid, spinal cord and brain--were removed from 43 seals at dissections performed on the german north sea coast. the specimens were fixed in formalin and routinely processed for light microscopy. the major pathological findings were lung: acute congestion with interstitial and intra-alveolar oedema; intra-alveolar haemorrhage; suppurative bronchitis and bronchopneumonia; larvae and adult ... | 1990 | 2365846 |
| a recombinant antigen-based enzyme-linked immunosorbent assay (elisa) for lungworm detection in seals. | pinnipeds are frequently infected by the lungworms otostrongylus circumlitus and parafilaroides gymnurus (metastrongyloidea). infections are frequently associated with secondary bacterial bronchopneumonia and are often lethal. to date, a reliable lungworm diagnosis in individual seals is only possible during necropsy as examination of faeces collected from resting places does not allow assignment to individuals. therefore, a diagnostic tool for lungworm detection in living seals is desirable for ... | 2015 | 26329933 |
| lungworm seroprevalence in free-ranging harbour seals and molecular characterisation of marine mammal msp. | harbour seals (phoca vitulina) are frequently infected with the lungworms otostrongylus circumlitus and parafilaroides gymnurus. the infection is often accompanied by secondary bacterial infections and can cause severe bronchopneumonia and even death in affected animals. hitherto, the detection of lungworm infections was based on post mortem investigations from animals collected within stranding networks and a valid detection method for live free-ranging harbour seals was not available. recently ... | 2016 | 26977405 |
